An interesting game with challenging puzzles. I didn't find any connection to the rest of the games from the developer but I still did enjoy playing it! Had to use the hint option quite few times, and as per the ads I don't mind them(1ad per time it's only normal) considering the fact that you have a nice game for free.

Second game from this developer I've played. Once again it feels deliberately obtuse to force you to watch ads for hints. Awkward translations (village called hidden town??). Liked it less than Nowhere House, quit early. I'm not saying it has to be easy. I like a hard puzzle. But if it's a hard sudoku at least you know exactly what the rules are. What you can and can't do with the items in this game is up to the developer so I have much lower tolerance for weird moon logic clues.

Definitely a little abstract but the puzzles do follow a logic within the game world. I was stuck for a long time at the start of the game because I didn't notice something fairly obvious. My advice would be to pay close attention to the objects in your inventory, including what they're made of or printed on. Overall, enjoyable, and it generated enough interest for me to want to try the other games in the series.
